Digital voltmeter with PIC16F877A using Proteus and Micro C

[@sifisokaula5032]

Good day Engineer Brandon.
I built the same circuit and it simulates perfectly except that it seems that it cannot display voltages below 1V properly. For example 0.1V will be displayed as 1V, 0.01 will also be displayed as 1V.
I did some digging and realised that the floattostr function is the cause. The sprintf function is a solution but the 16F877A does not support this function. How would you solve this problem. I see even in your video, you don't go below 1V

Great job

Can you help me here, can you display LM35 temperature sensor values on the LCD using AT89C51 microcontroller? LM35 must be connected to ADC0831. Can you do that conversion it is a challenge to me

[@musicwala3544]

Awesome explaining but your voice is very low please improve rest of that all goood

[@EngrBrandonstoolsEngineering]

I'll work on that. Thanks for the feedback.

Can it measure ac voltage ?

[@EngrBrandonstoolsEngineering]

No. The system measures only DC voltages

I'm not being able to find res1 register

[@papuixd5779]

hahha same bro

[@Phoenix007R]

@@papuixd5779 have any other suggestions?

[@EngrBrandonstoolsEngineering]

res1 isn't a register. It's a resistor. You can type res and get one resistor.

Same I cannot find it I search 2 day about this RES and i never had any info for that ... which Version of protuse use

how to save in hex file ya

[@EngrBrandonstoolsEngineering]

Once a code is built on Micro C IDE, the hex file is generated directly into the same folder where the code is saved
